Abstract

A lamp fixture comprising a first figurine mounted to a base and a second figurine connected relative to the base by means of a flexible member. A first lamp socket and a lamp shade are disposed at the top of a lamp pole. A second lamp socket is disposed within the interior of the first figurine. Movement of the second figurine to a first and a second position actuates an electrical circuit which supplies household current via a power cord to the first and the second lamp sockets, respectively, to light lamp bulbs contained therein. The electrical circuit comprises reed switches which are actuated by a magnet disposed within the second figurine. Each reed switch triggers a thyristor such as a triac or two silicon controlled rectifiers connected in parallel to provide a path for the household current to flow to the respective lamp socket. Movement of the second figurine to a neutral position precludes the household current from flowing to either the first or second lamp socket. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles or operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A lamp fixture for supplying electrical power from a power source to a lamp bulb, comprising in combination: a base;   a figurine mounted to said base;   a light pole mounted relative to said base;   a lamp socket mounted to said light pole;   a switch means;   means for connecting said switch means to said lamp socket;   a trigger means for triggering said switch means;   means for connecting said trigger means to said switch means enabling the switch means to supply power from the power source to said lamp socket while said switch means is being triggered by said trigger means;   a second figurine for actuating said trigger means;   said second figurine being disassociated from said trigger means such that said second figurine is not mechanically connected to said trigger means; and   said second figurine being movable in close proximity to said trigger means enabling said second figurine to actuate said trigger means while said second figurine is in a close proximity to said trigger means.   
     
     
       2. The lamp fixture as set forth in claim 1, further comprising in combination: a cavity disposed in said second figurine;   a magnet disposed in said cavity; and   said trigger means comprising a magnetically sensitive switch having electrical contacts which close when subjected to a magnetic field.   
     
     
       3. The lamp fixture as set forth in claim 2, wherein said magnetically sensitive switch comprises a reed switch. 
     
     
       4. The lamp fixture as set forth in claim 1, including a flexible member which connects said second figurine relative to the lamp fixture. 
     
     
       5. The lamp fixture as set forth in claim 1, wherein said switch means comprises a thyristor which is triggerable by said trigger means. 
     
     
       6. The lamp fixture as set forth in claim 5, wherein said thyristor comprises a triac; means for connecting the first main terminal of said triac to said lamp socket;   means for connecting the second main terminal of said triac to the power source; and   means for connecting said trigger means to the gate of said triac for triggering said triac into a conducting state thereby supplying power from the power source to said lamp socket.   
     
     
       7. The lamp fixture as set forth in claim 5, wherein said thyristor comprises a first and a second silicon controlled rectifier; means for connecting the anode of said first silicon controlled rectifier and the cathode of said second controlled rectifier to said lamp socket;   means for connecting the cathode of said first silicon controlled rectifier and the anode of said second silicon controlled rectifier to the power source; and   means for connecting said trigger means to the gates of said first and second silicon controlled rectifiers enabling said trigger means to trigger said first and second silicon controlled rectifiers into a conducting state thereby supplying power from the power source to said lamp socket.
